If children form 30 percent of a population and elderly people form 15 percent, what are the working-age share and dependent share respectively?

Answer and explanation

Correct answer: 55 percent and 45 percent

Children and elderly people are generally treated as dependent age groups for this calculation. Their combined share is \(30\%+15\%=45\%\). The working-age share is the part left after removing both dependent groups from the total population: \(100\%-45\%=55\%\).

Hence option A, 55 percent working age and 45 percent dependent, is correct. The order matters because the question asks for working-age share first and dependent share second. Option B reverses the two values. Option C does not follow from the supplied percentages, and option D ignores the elderly group while treating the children’s share as the working-age share.
